◆ 1: What is a tracking pixel?
Some e-mails use a technique called tracking pixels that collects the open status of the e-mail and the recipient's information by detecting the reading of the e-mail using a transparent image of 1 pixel. This technique itself is not illegal, but if tracking pixels leak information such as the recipient's IP address, it can be used in crimes such as phishing scams.
To prevent this, Google delivers Gmail attachments via its own proxy server, at least to prevent location tracking. In addition, extensions for blocking tracking pixels, such as Ugly Email and PixelBlock , have been released for Chrome and Firefox.
In addition, by taking a drastic measure of 'stopping emails from automatically loading images', it is possible to prevent tracking pixels from collecting information, although it is not possible to block all tracking. That thing. The setting method is as follows.
